Holiday dragons are a very mysterious breed. They are only seen during winter, and even then it is hard to catch a glimpse of one. They are responsible for the general cheer that spreads during the holidays. In essence, they are the “Spirits of Winter.”

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

You'll Buck, which isn't his real name, is one of "the other reindeer" when it comes to attitude. If anyone is different in some unusual way, he and his pals will make fun of and ostracize them. As soon as their master takes a shine to the outcast stranger, he immediately does a 180 and piles praise on them with feigned and disturbing glee, to stay in the master's good graces.
